Beijing News Yesterday, the National Climate Center released the 2020 China Climate Bulletin.
Song Lianchun, director of the National Climate Center, introduced that in 2020, my country's temperature will be relatively high, precipitation will be relatively high, and the climate year will be biased.
The Yangtze River Basin has experienced the most severe flooding since 1998, with heavy rain and flood disasters. The meteorological drought is generally mild, but the regional phase characteristics are obvious. The drought in autumn and winter in South China is more severe; the high temperature appears early and the south lasts longer; the landing typhoon is biased However, the landing location and time of impact are concentrated; the cold air has a wide impact range and the local temperature drop is large.
Compared with the average of the past ten years, the direct economic losses caused by meteorological disasters are more.
The average temperature last year was 0.7℃ higher than normal
The national annual average temperature in 2020 is 10.25℃, which is 0.7℃ higher than normal years (1981-2010) on average, making it the eighth warmest year since 1951.
Among them, the annual average temperature of Jiangxi Province, Zhejiang Province, Guangdong Province, and Fujian Province hit a new high since 1961.
On May 1-9, the earliest high temperature process since 1961 occurred in the central and eastern part of my country, 49 days earlier than normal.
From July 11 to September 3, there was a continuous high temperature weather process in southeastern Jiangnan and eastern South China, which lasted for the second longest time since 1961.
In 2020, there will be a wide range of cold air affecting our country and a large local temperature drop.
In November, heavy rain and snow hit the Northeast, the daily temperature drop in 9 counties and cities exceeded the historical extreme, and railways were shut down on a large scale.
The central and eastern part of December suffered a large-scale rain and snow cooling weather process, and the area where the temperature fell more than 12 ℃ was 1.184 million square kilometers.
The average precipitation is 10% more than normal
The communiqué shows that the national average precipitation in 2020 is 695 mm, 10.3% more than normal, and the fourth most since 1951.
Among the seven major river basins, the Songhua River, Huaihe River, Yangtze River, Yellow River, Liaohe River, and Haihe River Basin have more precipitation, and the Pearl River Basin is slightly less. Among them, Songhua River Basin and Yangtze River Basin both have the largest amount since 1961.
In 2020, there will be 37 regional rainstorms across the country. The number of rainstorm days is 24.1% more than normal, the second most since 1961 (second only to 2016).
The Yangtze River Basin has the worst flood since 1998.
In summer, both the Yangtze River Basin and the Yellow River Basin have the highest precipitation in the same period since 1961, and the Huaihe River and Taihu Lake Basin have the highest precipitation in the same period in history.
In 2020, my country's meteorological drought has obvious regional and phase characteristics.
From mid-April to early summer, there were staged droughts in many places north of the Yangtze River; in spring and summer there was a meteorological drought in parts of southwestern China; northeast and southern China encountered severe summer droughts; in autumn and winter, southern China and Jiangnan experienced meteorological droughts, which affected Zhejiang, Fujian and Guangdong. , Jiangxi and other provinces, agricultural production and water storage in reservoirs have adversely affected.
The rainy season hits a new high since 1961
In 2020, my country will enter a period of concentrated rainfall on March 25, 12 days earlier than normal; May 29, the plum blossoms, and August 2, the plum blossoms, the plum blossoms are early, the plum blossoms are late, and the plum rain lasts (65 Days) and rainfall (780.9mm, 127% more) both hit new highs since 1961.
The rainy season in North China, the rainy season in Northeast China, and the autumn rain in West China all started and ended late, and the rainfall was higher.
In 2020, a total of 23 typhoons will be generated in the Northwest Pacific and South China Sea, and 5 of them will land in my country, and the number of generated and landed typhoons is relatively small.
Among them, July was the first "empty platform" since 1949; from late August to early September, the northeast encountered a rare triple-hit typhoon in half a month, the first time since 1949.
In the spring of 2020, there will be 10 less sand and dust weather processes (7 times) in the northern region than in the same period of normal years.
The average number of dust days (2.6 days) was 2.4 days less than that in the same period of the year.
■ Tips
Prevent smog weather affecting transportation
The press conference reminded that the cold air activity affecting my country is expected to be weak in mid to late February.
In the west of the Beijing-Tianjin-Hebei region, the Fenwei Plain, the Yangtze River Delta and other places, the meteorological conditions of air pollution diffusion have phased deviations. It is recommended that the above areas prevent the adverse impact of haze on transportation.
In Northeast China, eastern Inner Mongolia and other places, the temperature is relatively low and the precipitation is relatively high. Animal husbandry and facility agriculture need to prevent the hazards of severe temperature drop, heavy snowfall and strong winds.
In most northern winter wheat areas, the temperature is normal or high, and the precipitation is normal or slightly higher, which is beneficial to increase the moisture content of the wheat field and the safe overwintering and green growth of winter wheat.
It is recommended to strengthen field management to ensure the safe overwintering and normal return of winter wheat.
In southern Jiangnan and southern China, where the temperature is relatively high and the rainfall is increasing, the weather conditions are generally favorable for early rice planting and seedling breeding. It is necessary to use favorable weather conditions to carry out early rice planting and seedling work in a timely manner.
In some areas of Southwest and South China, the temperature is relatively high, the precipitation is relatively low, and the meteorological level of forest fire danger in some areas is relatively high, and it is necessary to strengthen prevention.
